This document provides information on the datasets provided in this repository. 
Each excel file with the appropriate figure number in the paper where that data is represented has been mentioned.

File "Vertical_RH_Grand_data" (Fig. 1a)
shows the raw data for the floral humidity of individual flowers in the different levels of background humidity (column names).
The floral humidity shown is the %RH above ambient, in other words, the ambient RH has been subtracted. 

File "Tucson_datura_RH" (Fig. 1b)
Floral humidity of flowers sampled in Tucson, Arizona, USA, at the flower opening and in the floral tube 

File "Floral humidity manipulations" (Fig. 1c and 1d)
Floral humidity transects of control and flowers with manipulations. Note that some of the transects of control flowers are the same as Fig. 1a. This is because they were pooled 
from multiple experiments to represent floral RH at different background RH in Fig. 1a. This has been mentioned in the figure legends of Fig. 1 and also in the method section of the paper. 

File "stomatal distribution" (Fig. 1e)
The raw data of the Stomatal distribution shown in Fig. 1e. and supplementary Fig. 1d

File "Electrophysiology data" (Fig. 2)
The raw data file for the electrophysiology traces and the stimulus shown in panels g to l of Fig 2 in the manuscript.

File "Artificial_flower_humidity_transect" (Fig. 4b)
The raw humidity transect of the humid artificial flower used in the binary choice assays (Fig 4 and 5 of the manuscript).
Sheet 2 and 3 of this excel file contains the raw data for floral humidity of only standing nectar or water pools in an artificial flower (Supplementary fig. 1c).

File "probing duration" and "number of entries" (Fig. 4 e-l and Fig. 5 g-l)
Contains all the raw data of the binary choice experiments for two reponse variables of moths: probing duration and the number of entries in the humid vs. ambient flowers. 

File "Probing duration before nectar discovery and energy calculations" (Fig. 5a-c)
Contains the raw data for moth behavior before nectar discovery in the rewarded binary choice assays (Fig 5).
